ABSTRACT:
An apparatus for actuating and locking each pair of hopper doors of a railroad hopper car of the type having a plurality of hopper doors arranged in opposed pairs and extending transversely of the hopper car center sill. Each door actuating and locking apparatus for each opposed pair of hopper doors comprises a shaft assembly extending transversely of the hopper car between its respective opposed pair of hopper doors and through the hopper car center sill and the inner and outer hopper sheets for those hopper doors. That portion of the shaft assembly located within the center sill has an L-shaped lever structure non-rotatively mounted thereon. The lever structure is connected by links to the hopper doors of its respective pair. Either end of the shaft assembly can be engaged externally of the hopper car by an approriate tool to rotate the shaft assembly and its lever structure between a door open position and an over-center, door-closed and locked position.
